1986 Suzuki GS 450 won't start

Just bought bike. Had been sitting for three years but shows only 9,800 miles. All electricals work. Installed new battery, new plugs, bled carb bowls (fuel was nasty), cleaned fuel tank, and added fresh gas. Cranks but won't start. No gas to cylinder. Poured a dot of gas in cylinder and it fired but won't run. Side stand light is on in speedo. Got any ideas?

    I am wanting to buy this bike but it has been sitting for two years. I put fresh plugs in it, fresh gas and a good battery, we had power but the starter would not do anything at all. any suggestions, can the starter be jumped out so I can see if the engine runs or not. also where is the starter located on the bike?

Take the carburetors apart and either rebuild them or clean them thoroughly.

Hi, I have a 1982 gsx 1100 Suzuki sitting on the bike from left to right what is the firing order if left coil is 1-3 & right coil is 2-4? thanks

Hi, Nigel "Fast Cat" says all the inline fours are the same in this (that I know of, maybe BMW does it differently, but every Japanese inline-four I ever saw was the same) sitting on the bike, from left to right, the cylinders are 1-4... there are two coils, and the one coil fires cyls 1 and 4 and the other fires cyls 2 and 3. you can swap 1 and 4 or 2 and 3, it makes no difference at all, but you can't put the 2-3 coil on cyls 1 or 4 and vice versa... you should be able to just take the long spark plug wires and put them on cyls 1 and 4 and the shortys go to cyls 2 and 3. Firing order is 1-4-2-3 For more information about your issue and valuable "FREE" downloads that you will need please click on the links below. Good luck and have nice a day.

Engine revs out of control

check the inlet rubbers between the carbs and engine for cracks or hardening as an air leak here could be the source of your problems...

Why won't 1981 suzuki gs 550 bike won't start after riding it and it's warmed up?

glad i served a long time with wisco and used drag raced for them at one time
sounds to me that your ignition is to far retarded
which means the ignition will spark closer to (TDC)
top dead center
some people advanced the ignition 3 deg to stop the engine from smoking when they did away with 4 star fuel
and gave us unleaded fuel
doing this the performance is great and fast acceleration
but it also make the engine run hotter than normal
unless you have up jetted the carbs
and fitted a non standard exhaust system
the whole idea is get the fuel/air mixture in and out as fast as possible

if you still have points
take your points cover off and adjust your points baseplate
undo the three screws that hold it in place
and just move it about 3 deg towards the rear of the engine
or may be you have a electronic ignition fitted
if so do the same thing
and advance the ignition 3 deg

hope this works for you

ride safe

I have a 1992 yamaha seca 600.Bike was parked for 2 years.I cleaned carbs 2x.Bike idles fine ,but when I give it a little throttle it dies..Please help...I bought this thing to go to work..Ive put a lot of...

Sounds like you still have a fuel delivery problem...How did you clean the carbs? The jets, pilots, floats and circuits in these carbs are hard to get throughly clean. I use a small steel guitar wire to clean with...A tiny pin hole in the diaphram, or dirty or stuck choke circuit will cause problems.The floats need to be set correctly... I recommend an ultrasonic carburetor cleaning for best results. Consider installing carb kits, they are not very expensive and come with new jets, float valve needles and gaskets...The bike has been sitting 2 years, did you service the fuel petcock and flush and clean the gas tank?
Also the carbs need to be "synched" after they installed...all matched and in time with each other...check for vacuum leaks around the carb boots and cylinder head...check all the vacuum lines for any cracks or leaks....Check all your electrical connectors for signs of corrision, if they are dirty, clean them, they should all be shiny. Check your grounds, the main ground from battery to frame is a problem area... where it grounds to frame usually rusts and cant be seen until you remove it...A clean electrical circuit will provide you with a hotter spark at the plugs and improve performance.

These are good bikes, just take your time and go over it. She will be back on the road again in no time. I hope this helps---Good luck with your bike!

My bike has sat for one year. I bought a new battery one year ago and drove it from my old apartment to my current one. The bike has not been started for one year. I got a used gas tank on ebay and...

Ok mate few things to consider here, if the bike has been non started and stationary for a year there is a very good chance that one of the following or all of the following has occurred.
Your battery is dead (they don't like just sitting - doesn't matter new or old, if left for extensive time they will die) Your gear / motor oil would be useless - oil can not just sit in bottom of bike for a year it would be glue
Your carbi would be blocked or partially blocked from fuel gum or varnish in jets
If you like this bike I highly recommend oil and filter change, New spark plug (put about 10 drops of oil down the spark plug hole before you put new spark plug back in to lube the piston) clean air filter (or fit new one) Remove carbi and compressed air clean all jets especially the pilot jet and circuit and stick in a new battery
Once all done for the fist start I would find a nice safe hill and push start it. in my experience under this circumstances if you rely on the electric starter you may find you burn it out trying to start so give at least few minutes running motor to flush everything through before trying to electric start would be your best bet
When you get it going I would dump the oil and oil filter again after 2 hours ride time to confirm all the old expired oil is flushed out - just to be safe
good luck regards Jamie

I just bought a 1988 Yamaha Radian that has been sitting for about 5 years. Very clean conditions, looks show room ready. I have put about 200 miles on it. One day i was riding about 60mph when the bike...

I would suggest that you drain all four carburetors. The drain plugs are on the float bowl at the bottom of each carb. My guess is that condensation in the gas tank has made it's way into the carb (s) and bikes don't tend to run well on water. Clean the air filter while you are at it. Please rate my answer.

Take your carb off and apart and clean it throughly. Check your float to make sure its not getting stuck. If it ran fine befor do not tamper with the adjustment. Just free it up with lube then spray it clen with carb cleaner or starter fluid
